Cold or Slow Composting

With cold or slow composting, you can pile grass clippings, dry leaves and kitchen leftovers on the ground or in a bin. This requires no real maintenance, but it will take several months for the pile to decompose.
Cold composting will suffice if you don’t have much time to take care of the compost pile at least every other day, have small amount of yard waste, or you are not in a hurry to use the compost.
It is best to Keep weeds and diseased plants out of the mix since the temperatures reached with cold composting may not be high enough to kill the weed seeds or disease-causing organisms.
You can shred or chop your yard waste to speeds up the process. To easily shred material, use branch shredder or run your lawn mower over small piles of weeds and trimmings.
It is shown that Cold composting has better results at suppressing soil-borne diseases than hot composting.
Cold composting also leaves more undecomposed bits of material, which can be screened out if desired.
